Abstract
The effects of clipping off the 1/3-1/2 total leaf area at the emergence of 5,6,7 and 8 leaf,respectively,on the growth and physiological characteristics of flue-cured tobacco seedlings in floating system were studied by using the cv.K326 as experimental material.The results indicated that clipped seedlings showed stout stalks,heavier stem and root,greater root/shoot ratio and well-developed roots.Furthermore,clipping clearly improved the root vigor and the activities of the NR,SOD and INV,increased the active assimilation surface and the content of ascorbic acids,decreased the praline content and electrolyte leakage,indicating the seedlings had stronger resistance to stress.
